Abstract

Study on chloride ion adsorption and combined with the characteristics of sea sand concrete,through the determination of free chlorine ion content in sea sand concrete. The sea sand concrete microstructure and Friedel salt were characterized by using X-ray diffraction (XRD) , scanning electron microscopy (SEM) and thermal analysis methods (TG/DTA). Research results show that: the extraction temperature of solution is positively correlated with free chloride concentration in sea sand concrete. Physical binding of chloride ion in fly ash mortar shows low dissolution in lower temperatures. TG / DTA curve does not appear endothermic peak on the Friedel salt in sea sand concrete, while the XRD and SEM pictures show the existence of Friedel salt in the sea sand. Probably, it's the result of less Friedel salt, leading to the formation of the Friedel salt is unstable.
